Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://agents.citiviewgroup.com/v1/plan?goal=Find+10+coffee+shops+in+Toronto+and+put+them+in+a+spreadsheet'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://agents.citiviewgroup.com/v1/plan?goal=Find+10+coffee+shops+in+Toronto+and+put+them+in+a+spreadsheet' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
